SVBONY SV152 SWA Illuminated Eyepiece 20mm 70 Degree 1.25 inch for Guided Star Astrophotography

Surprised with the quality of craftsmanship of this product. Not only can it be used for star alignment but also for observation. It has a wide field of view making observation really enjoyable. The SV Bony customer service teal has been great in all the support that they provided.

I was surprised by the quality of craftsmanship for this eyepiece. Great field of view for observing the night sky and illuminator makes crosshairs stand out under dark skies making centering in the eyepiece really easy. Customer service team has been great and extremely responsive.

A great eyepiece not only for star aligning or tracking but also for observing. Good quality optics and an immense field of view. Makes observing a real fun. I was also surprised with the quality of Service from the svbony customer service team. Initially I received a product that did not work - illuminator was not coming on. I asked for a replacement illuminator and I was surprised to receive one week later a brand new eyepiece plus the illuminator. This company really knows something about impressing on their customers.

I ordered this eyepiece recently from SV Bony. Their customer care had been excellent. Initially I complained because the illuminator did not work but surprise surprise they sent me within a few days a brand new eyepiece with a working illuminator without asking me to send back the old one. I tested everything and was impressed with the wide field of view of the eyepiece and the illuminator itself makes centering on the cross hairs really easy. It has a potentiometer to regulate the illumination so it can be adjusted depending on conditions. Other products as I have read only have on-off illumination and cannot be adjusted. Thank you SV Bony for making good quality cost effective products and for providing such a great customers service.

Surprising that an eyepiece that is supposedly just for alignment turned out to be better than the ones that came with my 10" Newtonian. Does the job and I use it for other things as well. Have to give a should out to SvBony customer support. I dropped the illimitation tube and then stepped on it. When I contacted the company to buy a replacement, they replaced it for free and only had me pay the shipping costs. And they knew that the reason it broke was because I stepped on it and I offered to pay for the replacement. Five stars for this level of support.

This eyepiece was just what I needed in order to more accurately align my telescope to the stars when starting an observing session. This is well designed for this purpose, and it gave me excellent results in my first use for this. The illuminated crosshairs nearly eliminate parallax and other visual accuracy issues which occur when centering a star in an eyepiece during alignment. The wide field of view is helpful when initially looking for the target star. The optics are bright and clear. The crosshair illumination is variable over a very wide range, and gets quite dim at the lower end, so that dimmer stars may be seen. They are also bright enough to use in daylight at the upper end of the range. The crosshairs are narrow and well defined, which helps with precision. Overall build quality is very good. I am very pleased with this purchase.

This is one of the first eyepieces that I ever bought. Unlike many others, this one I continue to use routinely. It is an excellent value, giving wide field of views and sharp clear images. The adjustable reticule crosshairs are straight and as bright as you want to make them. I think this is an indispensable tool for any visual astronomer or planetary photographer. I highly recommend this high performance reticule eyepiece!
